And the stuff cavemen knew would be stuff a city boy like myself doesn't
have a clue about. How to hunt animals with nothing better than crude
spears and rocks, knowing what plants are safe to eat and what's
poisonous, etc.... Different environments, they didn't need to know about
car insurance.

I agree, stuff like how to walk upright, inventing the wheel, inventing fire
